This study demonstrates a compact optical modulation platform that enables real-time, high-resolution spectroscopy using sub-MHz interleaved combs generated via chip-scale acousto-optic phase ...

The lithium niobate thin-film modulator was designed to achieve a modulation frequency of 350 kHz within the 0–2π phase range, further realizing high speed control of optical field coherence.

Optical frequency combs constitute a transformative class of light sources that emit a spectrum of discrete, equally spaced lines spanning hundreds of terahertz. Generated most commonly by mode-locked ...

Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements.

Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair. Subscribe to our newsletter for the latest sci-tech ...
